Conanthewarrior Posted May 22, 2018 Report Share Posted May 22, 2018 Hi everyone, I am at the end of my tether with these mods, which I used to love. All four will not charge, and when I try to use them, I get either a check battery, or shorted message. One mod earlier worked for half hour, only to return to doing this. Is there any quick fixes for this? I highly doubt 4 of my mods have failed at exactly the same time, but then again out of 38 mods my Evolv mods have failed the most, requiring board replacements. Is there anything in settings that may be causing this? I have converted one to run on dual 18650's, the other 3 use li=Po's. I hope I can get some help, or I will likely just throw them away. Thanks, Conan. Link to comment Share on other sites More sharing options...
Conanthewarrior Posted May 22, 2018 Author Report Share Posted May 22, 2018 I would like to add I just fixed my DNA75, as the 510 positive lead needed re soldering. That is working perfectly, but none of my DNA200's are. I haven't used them In around a month, but surely not all 4 could have failed at once?

Spector NS5 RD Posted May 23, 2018 Report Share Posted May 23, 2018 Very strange @Conanthewarrior. For 4 DNA 200 mods to fail at exactly the same time is more than coincidence. If all 4 were working fine before this event there has a to be a common element; I doubt you're that unlucky. IIRC, don't you like taking the mods apart and tinkering around with the internals? swapping boards and rewiring them? Only thing i can think of is you tried something on the first mod, it didn't go well, and you kept trying it until you ran out of DNA mods. Honestly, that's the only scenario i can think of. Throw up some DM screenshots of all 4 mods trying to fire with all of the battery boxes ticked and the atty you were trying to use at the time of death and maybe we'll see commonality between the 4 mods, otherwise it's "ticket" time. 1 Link to comment Share on other sites More sharing options...
Conanthewarrior Posted May 23, 2018 Author Report Share Posted May 23, 2018 (edited) I havne't tried to tinker with them , the only one I have was a broken DNA75, this just needed the positive wire soldered back in place to the 510, and now works. I will just take some screenshots, my Wismec Relaeux triple 18650 after tinkering is working.I can't get the Efusion or Hotcig V2 and V1to work though, here are the screenshots-the V2 runs on dual 18650's. Whips- I didn';t fire. Two minites. Edited May 23, 2018 by Conanthewarrior Link to comment Share on other sites More sharing options...
Conanthewarrior Posted May 23, 2018 Author Report Share Posted May 23, 2018 (edited) Ok, the hotcig dual 18650 which is now firing - https://imgur.com/H4xHLD9 Efusion, not firing- https://imgur.com/cVv4fPv Hotcig V1 not firing- https://imgur.com/8F7lvXM Edited May 23, 2018 by Conanthewarrior not showing Link to comment Share on other sites More sharing options...
retird Posted May 23, 2018 Report Share Posted May 23, 2018 Links to your screenshots don't work.... Link to comment Share on other sites More sharing options...
Conanthewarrior Posted May 23, 2018 Author Report Share Posted May 23, 2018 (edited) Ive tried again using IMGr, done a direct link, could you try again? There are definitely working for me Edited May 23, 2018 by Conanthewarrior Link to comment Share on other sites More sharing options...
retird Posted May 23, 2018 Report Share Posted May 23, 2018 They now work since your edit....thx Link to comment Share on other sites More sharing options...
Wayneo Posted May 23, 2018 Report Share Posted May 23, 2018 Dead/dying batteries on both. Look at the cell voltages Link to comment Share on other sites More sharing options...
retird Posted May 23, 2018 Report Share Posted May 23, 2018 It seem that the common theme of the ones that don't charge is that all batteries are almost completely discharged.... setting on the shelf for extended times allows the batteries to drain as a very small current drains continuously but takes a long time to get to the point your's are at... when the voltage of the battery gets that low the charging circuit will not charge them.... you might try recovery... if that doesn't work replace the batteries...note that the recovery charging process takes a long time....

Conanthewarrior Posted May 23, 2018 Author Report Share Posted May 23, 2018 I have tried recovery charging, but it doesn't look like it is working- the Amps are at something like 0.020! Or is this really how long the recovery charge takes? I have 38 mods, so it is likely the batteries have become discharged as mentioned. I try to rotate my mods to use 5-10 each month, and wanted to use my DNA mods this month. I will keep recovery running and hope it works. I have a spare pack for the Efusion, but not for the Hotcig- the batteries are weird in a very small housing. Link to comment Share on other sites More sharing options...
retird Posted May 23, 2018 Report Share Posted May 23, 2018 Recovery takes a LONG TIME and most times it isn't successful and sometimes you have to run it more than once.... hopefully your spare pack isn't discharged also.... Link to comment Share on other sites More sharing options...
Conanthewarrior Posted May 23, 2018 Author Report Share Posted May 23, 2018 Right it is working for cell 3, it is up to 3V now, but the other two are falling- is this normal, and they will balance out by the end of the recovery? Link to comment Share on other sites More sharing options...
retird Posted May 23, 2018 Report Share Posted May 23, 2018 It should be balancing if the cells are able to be recovered...... Link to comment Share on other sites More sharing options...

Total waste of time posting but so funny, yes all three lipos could and would fail together. They are all one Mod with lipos behaving the same as each other. Standing (storage or how they come new) voltage for lipos is 3.8 volts, this needs to be checked regular, too high or too low and they will deplete, too low and they will die. Below 2.9 I believe will kill them. DNA 200 likes to be used, charged, used, charged, used, charged, they do not like to be left ignored. I know as have done exactly the same and they die. If your going to stop using them, disharge to 3.8 and check weekly. Do not just throw them away as any voltage left on them can turn them into a small bomb. Make sure you recycle them (give to hobby shop) or throw them in a bucket of salt water and leave them for a very long time. Proper lipo chargers can safetly disharge them fully. Then they can be thrown away safetly. Link to comment Share on other sites More sharing options...
